For the scientists, the Unified Field represents the union ofthe weak nuclear force and the powerful nuclear force with theelectromagnetic force and the force of Gravity.In the Great Union case, there is supposed the possibility ofthe union of the weak nuclear force (representing theelectronic cover of the atom) with the powerful nuclear force(representing the atomic nucleus composed by protons andneutrons) with the electromagnetic force. The nuclear forceand the electromagnetic force are milions and milions timesbiger than the Gravity force, negligible in this case.
